AIR-BLAST GRAlN-SPOUT.

SPECIFICATION forming part of Letters Patent No. 772,124, dated. October 11, 1904.

Application filed February 5, 1904. Serial No. 192,093. (No model.)

To all, whom, it may concern.-

Be it known that we, CHARLEs Gr. BENEDICT and WILLIAM ANDERS, residing at Creighton, in the county of Knox and State of Nebraska, have invented certain useful Improvements in Air-Blast Grain-spouts; and we do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part ofthis specification.

This invention relates to a new and novel improvement in air-blast grain-spouts.

The aim of our invention is to provide a device by means of which grain may be expeditiously loaded into a grain-car, the hulk of a vessel, or any other suitable receptacle by means of an air-blast; and our invention embodies the combination of certain mechanical instrumentalities, as will be set forth more fully hereinafter, and finally pointed out in the claim.

In the accompanying drawings we have shown in Figure 1 a view, partly in section and with portions broken away, of an airblast grain-spout embodying our invention.

Fig. 2 shows a rearview of the adjustable nozzle as used in our invention, disclosing the intake-opening. Fig. 3 shows a sectional View of the fan. Fig. 4 discloses a top View of the fan and spout as used in our invention, while Fig. 5 discloses a top view illustrating the grain-spout as branched.

In Fig. 1 we have shown a broken portion of a grain-elevator A, within which is provided a suitable support 1, held by a cleat 2. Upon this floor 1 are held the brackets 3, which brackets support a suitable blast-fan B. In Fig. 1 one side of the blast-fan is shown as removed. These brackets 3 support a suitable shaft 4, provided with a plurality of fanblades 5, these fan-blades being secured near their sides by means of two disk flanges 6, as shown also in Fig. 3. These fan-blades 5 are secured to the spokes 1 of the fan-wheel, as disclosed. Secured to the sides of the fan are the gates 7, as disclosed more particularly in Fig. 4, so that the amount of air taken into the fan may be regulated. Secured to the exit-spout 8 of the fan B by the'joint-piece 10 is the air-tube 9, which tube may be of metal and be straight, as is shown in Fig. 1, or be curved, as is shown in 9 of Fig. 4. In order that this tube 9 may be adjustable, the same is made to telescope, so that this tube 9 will telescope into and out of the joint 10. The outer end of this air-tube 9 is somewhat contracted, so as to fit into the delivery-nozzle D, as is disclosed more particularly in Fig. 1. This delivery-nozzle D is provided,

-in addition to the intake-opening a, as is disclosed in Fig. 2, with the second grain-intake opening 5, as is more clearly disclosed in Fig. 2, into which opening extends the grain-delivery spout K, which is suitably secured to the grain-bins or grain-weighing mechanism and from which the grain is to be fed intoa suitable car -M, as shown in Fig. 1.

The adjustable nozzle D is provided near the forward end with the ears 12, to which are secured the supporting-rods 13, swivelly supported below upon the pin 14, held within the bracket 15, secured to the bifurcated car 17, striding the grain-door 16, as indicated in Fig 1. Extending from this bifurcated ear 17 is a supporting-rod 18, provided with the socket 19, within which operates the ball 20 of the bracket 21, secured to the adjustable nozzle D. The supporting-rod 13, it will be noticed, is provided with the section 13, the

two being slotted and united by means of the '1. Now if it is desired to deliver the grain toward the end of thevcar the nozzle D is adjusted so as to extend to the left orright, in which instance, however, we use a curved airdelivery spout or tube 9', as is disclosed in Fig. 4. When that end of the car is filled,

the tube 9 is reversed, the nozzle D being re adjusted so that the grain may be fed toward the end of the car. If desired, the air-tube 9 may be provided with two ends, as shown at 0 in Fig. 5, so that the air may be simultaneously forced to the right or left, the nozzle being provided with a suitable grain-intake opening 6, as is shown in Fig. 5. This grainintake opening is shown at the juncture of the two branching pipes, though it should be understood that the same may be placed at the ends of these pipes 0. If desired, the nozzle D may be secured to a swivel-collar 26, provided with a ring 27, suitably supported so that this grain-delivery nozzle may be turned upon the end of the spout in feeding the grain toward the end of the cars. It is of course understood that these air-blast deliver y-spouts may be made of various sizes. In Fig. 1 a

asin position, supporting the bifurcated end of the bracket 18.

Having thus described our said invention, what we claim as new, and desire to secure by United States Letters Patent, is

The combination, with an air-blast fan, of an air-duct leading from said fan, a nozzle secured to said duct, said nozzle being adjustable in a horizontal plane, adjusting-brackets to support said nozzle, a grain-intake opening within said nozzle and a grain-delivery spout entering said nozzle.

In testimony whereof we aflix our signature in presence of two witnesses.
